Question

a student says that if 5x^2 = 20, then x must be equal to 2. do u agre or disagree with the student? justify your answer.​

Answer 1

The student is correct.

Explanation:

Given that 5x² = 20:

It is true that the value of x = 2 because 2² = 4, and when you multiply 4 with 5, you'll get a product of 20:

5x² = 20

5(2)² = 20

5(4) = 20

20 = 20

Therefore, the student is correct that x = 2.
